coal-fired fuel and hot water output wood boiler

Steam coal-fired fuel and hot water output wood boiler is one of the indispensable devices in the pharmaceutical industry, decoction of Chinese medicine, medicine drying, sterilization, cooking gum, drying, tabletting and capsule production processes, a large amount of steam will be used. West Libang Pharmaceutical Co., Ltd. is a pharmaceutical research and development, production and sales of high-tech enterprises, the existing anesthesia, cardiovascular, child immunization, pharmaceutical raw materials, pharmaceutical excipients, nutrition series of six automated production lines. With the increasing strength of China's environmental protection, some high-pollution devices are making the transition to clean environmental protection. Libang Pharmaceutical respond positively to national coal to gas policy, decided to change the existing coal-fired boilers to clean better gas steam boiler. Fast boiler with strong comprehensive strength in the field of clean energy, Libang Pharmaceutical after conducting comprehensive consideration, determined to cooperate with the fast boiler. The two sides further understanding, party fast technical engineers according to production needs state power, and soon its development of specific solutions for its recommendation of a 6 tons of steam condensing gas steam boiler (WNS6-1.25-Y.Q).

Our coal-fired fuel and hot water output wood boiler is mainly about horizontal steam boiler and industrial hot water boiler, according to different fuel, the suitable boiler have biomass boiler, coal boiler, gas boiler, oil boiler. In most plant and factory, 1-35 ton steam boilers and hot water boilers is enough.

Run chemical plant coal-fired fuel and hot water output wood boiler problems that may arise is what chemical plant boiler operation possible problem is? There are two main chemical plant boiler evaporation: evaporation and rated maximum continuous evaporation. When the chemical plant boiler load is higher than the maximum continuous evaporation, it indicates the operating force or overload. The following problems may occur super-load operation: Main results are as follows: (1) due to increased fuel consumption, furnace volume heat load increases, the furnace temperature and furnace flue gas outlet temperature, resulting in the superheater and reheater the superheated steam temperature and wall temperature, and must therefore be strictly monitored and adjusted. Try not to let this time overheating. Coal furnace, furnace volume due to the increased thermal load, increasing the likelihood of slagging. (2) the flow rate of chemical evaporation apparatus system working fluid increases, the flow resistance is increased, it is not conducive to water circulation. Therefore, we should pay particular attention to the monitoring of the water cycle bad area. (3) the pressure differential between the drum and the superheater outlet flow increases as the working fluid and superheater flow resistance increases, so that the pressure of the steam drum and headers increases, the strength of these components must be considered . Space volume load (4) the steam drum, the load increases the evaporation surface, saturated with water vapor would increase, thus affecting the quality of steam. (5) chemical plant boiler safety valve Total displacement designed according to a maximum continuous evaporation. If the chemical plant boiler overload, once the sudden load shedding, the safety valve will not fully open, the steam pressure can not be reduced quickly. At this point, it is necessary to ensure the safety of the boiler by chemical vapor released into the air exhaust valve. (6) With the increase of the amount of air required for combustion and the amount of smoke produced, once sufficient air supply, the air volume is insufficient, the chemical conditions affecting the combustion boiler, increasing the likelihood of slagging; In addition, since the flue gas velocity the increase in fly ash increased the degree of wear of the heating surface. (7) during operation, the exhaust gas temperature rises, the exhaust gas heat loss; shorter residence time in the furnace the fuel, incomplete combustion heat loss of mechanical and chemical incomplete combustion to increase the heat loss, reduce the thermal efficiency of the chemical plant boilers. In summary, the excess chemical plant boiler operation have an adverse impact on the security and economic, should generally not excessive run. If the special emergency must also be strictly limited scope and excess power beyond the time required to force.

Industrial coal-fired fuel and hot water output wood boiler energy saving measures which are currently the main problems of industrial boilers have low thermal efficiency of boilers, energy can not be effectively utilized, resulting in waste; old boilers, automatic control level is not high, affecting boiler combustion efficiency; energy-saving regulation in place, and many other issues . In order to prevent pollution of the environment, reduce energy consumption, industrial boiler energy saving technical measures as follows: (1) the transformation of coal to the device. The modified ingredients bucket coal to the coal layer, using gravity filtering, the pulverulent raw coal, lump coal from top to bottom on the grate loosely distributed, facilitates air intake, improve combustion, improve the combustion rate of coal, reduced ash carbon content. (2) the transformation of the combustion system. For forward Stoker, the transformation from a combustion system is injected into the furnace in place an appropriate amount of pulverized coal to the furnace in place, so that the combustion grate base layer, the increase amount of suspension firing. (3) the transformation of furnace arch. According coal actually used, appropriately changing the shape and position of the furnace arch, can improve combustion, improve the combustion efficiency. (4) Transformation of grate-fired boiler circulating fluidized bed boiler. Employ a circulating fluidized bed boiler is a pulverized coal boiler in the furnace of the circulating fluidized combustion mode, which is 15-20% higher than the thermal efficiency of the boiler burning layer. For a variety of coal, limestone powder may be used in the furnace desulfurization, greatly reducing the content of the flue gas emissions of S02. Using (5) inverter technology, auxiliary boilers transformation. (6) The automatic control system, real-time adjustment of the heat output of the boiler, to save energy. (7) recovering the condensed water. (8) boiler replacement, replace old boiler with a new boiler. (9) flue gas discharge system reform.
